APPLICATION OF LOCAL BIOIMPEDANCE ANALYSIS FOR EVALUATION OF SUBCUTANEOUS AND VISCERAL FAT DEPOSITION IN THE ABDOMINAL AREA IN UNIVERSITY STUDENTS

Abstract

Objective - to study the efficiency of the local bioimpedance analysis for the assessment of subcutaneous and visceral fat deposition in the abdominal region in university students using domestic bioimpedance equipment. Material and methods. Cross-sectional clinical epidemiological study of 103 medical students of the Peoples’ Friendship University of Russia (42 males and 61 females) aged 19-34 was conducted. Bioelectrical impedance analysis was applied using a conventional whole-body «wrist-to-ankle» measurement configuration and two local measurement configurations in the abdominal region for the assessment of subcutaneous and visceral fat according to Scharfetter et al. (2001) and Ryo et al. (2005), respectively. The majority of the study subjects (68,9 %) were within the normal BMI range. Results. Maximal correlations of the skinfold thickness with local resistance parameters (Spearman rho=0,90 for males, 0,88 for females) were higher than with the waist circumference, body mass index and bioimpedance body composition estimates (0,85 for males, 0,77 for females). Conclusions. Our results demonstrate possibility of more accurate, as compared with the conventional markers of body fatness, assessment of subcutaneous fat using local bioimpedance measurement. Combined use of the reference method (e. g., computed tomography) and bioelectrical impedance spectroscopy is necessary to evaluate an effectiveness of the visceral fat assessment, to check and refine the respective predictive formulae, and to optimize measurement frequency range.
